Air Filter Efficiency – What Is It and How Is It Measured?

We are often asked how well our air filters clean the air supplied to the engine for combustion. This may be when customers are looking to improve their current air cleaner.

A common question is: “what micron rating is it?”. However, a micron rating is an efficiency measurement used for liquid filters and not used for describing air filter efficiency.

Air filter elements are evaluated using an industry wide standard (ISO5011) and their performance is expressed as an efficiency level.

This efficiency level is determined by feeding air containing a known concentration of standard test dust into the air cleaner until the filter reaches the end of its life. This end of life is when the restriction reaches a predetermined level. The use of a standard test dust ensures consistency and is representative of the size range of dust particles found in real conditions.
When the filter reaches the end of its life, the weight of the dust on the filter is considered the capacity of the filter. Any dust, which passes the filter, is captured by an absolute filter down stream of the air cleaner in the test laboratory.

The weight of the dust captured by the absolute filter is compared to the weight of the dust fed into the air cleaner. The difference between them is the efficiency of the filter expressed as a percentage.
